GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 266,676, dated October31, 1882.

Application filed March 18, 1882. (No model.)

To all whom it may concern:

Be it known that we, SIDNEY 000K and JoHN HENRY PIPER, citizens of theUnited States, residing at Boston, in the county of Suffolk andStateofM-assachusetts, have invented certain new and useful Improvementsin Gas- Burners; and we do hereby declare the follow ing to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersor figures of reference marked thereon, which form a part ofthisspecification.

This invention relates especially to gas-burners in which the gas issuperheated by its own flame, in order that it may reach the burners inthe best possible condition for perfect coinbustion.

The drawings accompanying this specification represent, in Figure 1, asectional elevation, and in Fig. 2 a part bottom view and parthorizontal section, of a burner containing our improvements, said viewbeing taken looking upward and Fig. 3 in such drawings is a verticalsection on line 2 z of Fig. 4, the upper part corresponding to avertical section on line z z of Fig. 1, and Fig. 4 a horizontal sectionon line 00 m ofFig. 3, of an Argand burner containing our improvements,the latter view being represented looking upward. Fig. 5 represents anenlarged vertical section of a part of an Argand burner similar to thatshown in Fig. 3, to which our invention has been applied.

Reference being had to Figs. 1 and 2 of the above-named drawings, A willbe seen to represent the inlet end of a gas-distributing pipe, the upperextremity of such pipe terminating in a hollowsemi-spherical head orbulb, B, having aseries of peripheral openings, (0 a, 850., in its upperpart for escape of gas entering such bulb from the pipe A.

Surrounding the bulb B will be seen a semispherical closed drum, O, terminating at bottom in a tubular hub, 12, which, at its extreme lowerpart, tightly incloses the gas-pipe A, this hub Z) containing a series(preferably four in number) of ordinary gas-burners, c c, 850.,radiating from it and communicating with its interior. Gas admittedunder pressure to the pipe A flowsinto the bulb or head B, thence by wayof the openings a into the chamber 0 and annular hub 11, and finallyissues at the burners, provided the cock of the pipe A is open. The jetsof gas from the burners being ignited, the heat from the flame radiatesabout the exterior of the drum 0, and superheats the gas in its transitthrough such drum, the gas being thereby presented to the burners in thebestcoudition to obtain the most effective combustion and the highestillumination. Coal-gas, if con sumed too rapidly to allow time for thescpiration and ignition of its carbonaceous matter, loses inilluminating-power. By the employment of the drum Uas a receiver for thegas We permit such gas to expand, and by sealing the drum weprovideagainst the admixture of air and gas, which would accelerate thecombustion to too rapid an extent. Theheat evolved from the inflamed gasat the burners flows about the exterior ot'the drum 0 and heats theinterior of the latter to a high degree, and thus converting such drumintoa heater, which serves to superheatthegasand presentthelatter totheburners in the most favorable condition to secure active combustionof its carbonaceous matter. For the same reason the perfect combustionof gas at the burner heats the carbon of the gas to whiteness, therebyimparting the highest illuminating-power. Until the gas inflamed at theburners has imparted the requisite degree of heat to the interior of thedrum (J, a certain amonntofcarbon is precipitated from the flame uponthe exterior surface of the drum, and more or less carbon may be thusdeposited at times from unavoidable causessuch as undue draft of air,&c.-no matter how perfect the combustion is in other respects. 'loeffect- U2LllyI6ll10V6 and utilize this carbon, we connect with the drum0, preferably by erecting the same upon its top, a closed cup or vessel,D, which constitutes a miniature steam-generator, this vessel having asuitable fillingorifice, d, and being provided preferably with a steamspace or dome, e, from which a cluster or series of pipes, f f, &c.,lead, and descend into and through the lower part of the drum 0 or theannular bore of the huh I), as shown in the drawings, and terminatingupon the outside of the latter. Should carbon collect upon the exteriorof the drum 0 to any appreciable extent, a small quantity of water isrendering suchcarbon combustible and utilizing it to aid in heating thesaid drum. The pipes f may be led about the outside of the drum Gin lieuof through it, as shown; but we prefer the former arrangement. So, too,

with regard to the apertures ct of the bulb B,

in lieu of being in the periphery of the latter, as shown, they may bein the top thereof, a space beingprovided in this case between such topof the bulb and of the drum (3.

We do not confine ourselves to the exact construction or arrangement ofthese details, or to the precise construction and relative dispositionof the bulb and drum, as we consider our invention in this respect toconsist in the combination, with a gas-pipe, of a receiver in which thegas is allowed to expand, and, in heating this receiver by suitablemeans, to superheat such gas in its transit to the burners.

In Figs. 3, 4, and 5 of the drawings we have shown an Argand or annularburner adapted to receive our improvements. In this instance thegas-pipe A, bulb B, drum 0, generator D, and steam-pipe f are employed,as in Figs. 1 and 2; but in .lieu of the burners c we employ an Argandburner of original construction. The body of this burner is acylindrical or annular tube or chamber, E, in the upper edge of which iscreated a contracted annular opening, g, or a series of holes, ifpreferred, while the upper mouth of this annular chamber or tube E isinteriorly screw-threaded, as shown at h, to receive theexteriorly-screw-threaded shank i of an annular plate or ring, j, thebody of which is situated over the orifice g of the chamber E. Byturning the ring j in its seat in one or the other direction the amountof gas allowed to escape is regulated.

The burner-bodyE intercom municates at its lower part with the interiorof the drum 0 by radial pipes cl d, uniting the two, while the airrequisite to support combustion is supplied through the center of thebody E and annular cap The exterior of the drum 0 may be polished andplated to provide a reflecting-surface, and

furnished with a globe or shade, the whole presenting a highlyornamental appearance.

Theprincipleof ourinvention may obviously be applied,by slightmodifications ofconstruction, to Argand burners ot' the ordinary sort.

We are aware that it is not new to combine with a gas-pipe a compartmentsupplied by said pipe at the bottom, an incasing-drum which communicateswith said compartment at the top, and burners which heat said drum, andtherefore we do not claim the same.

What we do claim isl. The upper closed cup or vessel, D, in combinationwith the bulb B, the drum 0, surrounding said bulb and communicatingtherewith by openings a, and the supply-pipe and burners,allsubstantially as set forth.

2. The combination, with a gas-supply pipe and a receiver connectedtherewith, to permit of expansion of the gas and heated by the gasinflamed at the burners attached thereto, of a steam-generator heated bysuch drum, and provided with steam-delivery pipes which deliver thesteam from such generatortoapoint where it shall mingle with the flamesof the burners.

3. In combination, the gas-supply pipe, the inner perforated receiver,the outer superheating-drum, the gas-burners connected with such drum,and the steam-generator connected with and heated by such drum.

4. In combination with a gas-supply pipe, a receiver which allowsexpansion of the gas from said pipe, and an Argand burner consisting ofan annular body or chamber, a pipe or pipes communicating with thesupply-pipe, and a cap or cover adjustable on the outlet of said chamberto regulate the flow therefrom, said burner being located in proximityto the receiver, in order that the burning gas may heat the latter andits contents.

5. The combination, with the Argand burnor, consisting of the circularbody or chamber, the annular cap screwing into the same and governingits gas-outlet, and the radial pipes connecting the annular chamber withthe gassupply pipe, of the inner perforatedreceiver, the outersuperheating-drum communicating therewith, and the steam-generator, withits steam-delivery pipes arranged to-direct the escaping steam to theflame of the burners.

in testimony whereof we affix our signatures in presence of twowitnesses.
